Project: Al Madina Al Shamaliya Sewage Treatment Plant in Bahrain
Description of works:
PCC was a subcontractor to Wabag-Belhasa JV WLL for the construction of the Sewerage Treatment Plant.
The works carried out consisted of the construction of buildings, including civil architectural finishes.
Construction of 21 m deep TLS structure, including dewatering, erection of specialized formworks.
The process scheme begins with the inlet chamber and an 85,000 m3 per day terminal lift pumping station which sits at a depth of 21 metres. The water from the deep sewage gravity network is pumped through this depth with the help of a dry well pump.
Including all the external hard landscape works.
Executing this project was a huge challenge as it was situated on reclaimed land surrounded by sea from three sides and a hill in the middle which proved to be a bottle neck for construction.
The project stands out as a structural marvel with 25,000 cubic meters of concreting and reinforcement of over 7,000 MT of steel. The 85,000 m3 per day deep terminal lift pumping station sits over 160 piles carefully inserted over an unstable surface which housed an aquifer below it.
Despite all these challenges, no compromise was made on safety and quality. With an eye for customer satisfaction, Poullaides Construction Company & Wabag overcame these challenges and completed the project on time, clocking a total of 3.5 million safe man hours.
